13. Connector Pinouts

XLR jacks of analog input / output
The XLR connectors are wired according to international standards:
1 = GND (shield)
2 = + (hot)
3 = - (cold)
TRS jacks of analog input / output
The stereo ¼" TRS jacks are wired according to international standards:
Tip = + (hot)
Ring = – (cold)
Sleeve = GND
The servo-balanced input circuitry allows to use monaural TS jacks (unbalanced) with no loss in
level. This is the same as when using a TRS-jack with ring connected to ground.
The jack sockets of the two outputs are unbalanced, but realized as TRS. Since the contact R is
connected to ground with 100 Ohm, virtual balanced connections to these sockets are also
possible.
TRS Phones jack
The analog monitor output on the front
is accessible through a stereo ¼" TRS
jack. This allows a direct connection of
headphones. In case the output should
operate as Line output, an adapter
TRS plug to RCA phono plugs, or TRS
plug to TS plugs is required.
The pin assignment follows interna-
tional standards. The left channel is
connected to the tip, the right channel
to the ring of the TRS jack/plug.
Cinch / RCA
By a simple adapter mono 6.35 mm to RCA (also called Phono and
Cinch). The adapters are plugged into the rear inputs and outputs -
done. Now the existing RCA cables can be used with the ADI-2 FS.
Cables with mono 6.35 mm on one side and RCA on the other also exist, and work perfectly.
